title: Trapezius transfer after brachial plexus palsy. Indications, difficulties and complications.
abstract: Most brachial plexus palsies are due to trauma, often resulting from motorcycle accidents. When nerve repair and physiotherapy are unsuccessful, muscle transfer may be considered. Paralysis of the deltoid and supraspinatus muscles can be addressed by transfer of the trapezius. Between March 1994 and June 1997 we treated 38 patients with brachial plexus palsy by trapezius transfer and reviewed 31 of these (7 women, 24 men) after a mean follow-up of 23.8 months (12 to 39), reporting the clinical and radiological results and subjective assessment. The mean age of the patients was 29 years (18 to 46). The operations had been performed according to the method of Saha described in 1967, involving transfer of the acromion with the insertion of the trapezius to the proximal humerus, and immobilisation in an abduction support for six weeks. Rehabilitation started on the first postoperative day with active exercises for the elbow, hand and fingers, and electrical stimulation of the transferred trapezius. All 31 patients had improved function with a decrease in multidirectional instability of the shoulder. The average increase in active abduction was from 7.3 degrees (0 to 45) to 39 degrees (25 to 80) at the latest review. The mean forward flexion increased from 20 degrees (0 to 85) to 44 degrees (20 to 90). Twenty-nine of the 31 were satisfied with the improvement in stability and function. Trapezius transfer for brachial plexus palsy involving the shoulder improves function and stability with clear subjective benefits.
